Hi all, I have been working with VMware for a while but am a newbie in Xen. I''ve installed xen-3.0 and tested the result with ttylinux successfully. Now, I am trying to build a virtual machine from scratch but kernel panics with the following messages when starting new domain: xentest >xm create -c xm-rhel4 Using config file "xm-rhel4". Started domain rhel4 Linux version 2.6.16-xen (xenod@freefall.cl.cam.ac.uk) (gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)) #1 SMP Thu Apr 13 18:46:07 BST 2006 BIOS-provided physical RAM map: Xen: 0000000000000000 - 0000000020000000 (usable) 0MB HIGHMEM available. 520MB LOWMEM available.
